DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will now be described with some preferredembodiments thereof and by referring to the accompanying drawings. Forthe purpose of easy to understand, elements that are the same in thepreferred embodiments are denoted by the same reference numerals.

Please refer to FIGS. 1 to 3. A pull-out aiding device 100 according toa first embodiment of the present invention is configured for mountingon an object, which includes a first partitioning wall 210 or/and asecond partitioning wall 220 located opposite to each other. In theobject, a corresponding apparatus 300, such as a hard disk, can bemounted. The object also includes a top wall and a bottom wall (notshown), which are connected to the first and the second partitioningwall 210, 220. That is, the first partitioning wall 210, the secondpartitioning wall 220, the top wall and the bottom wall together definea receiving space, in which the corresponding apparatus 300 is received,and an opening communicating with the receiving space. A circuit board400 is arranged in the receiving space and has a connection port 410provided thereon for connecting to a corresponding connection jack (notshown) on the corresponding apparatus 300, such as a hard disk.

The object can be, for example, a chassis, a drawer, a hole, a recess, acover or a wall panel.

The pull-out aiding device 100 includes a pulling member 110 and ahandle member 120. The pulling member 110 is movably coupled with thefirst partitioning wall 210, and includes a first pivot section 111 (seeFIG. 4) and an abutting section 112, which are located at two oppositeends of the pulling member 110. The abutting section 112 is abuttedagainst the corresponding apparatus 300 for pushing the latter forward.The handle member 120 includes a pressing section 121, a second pivotsection 122 and an operating section 123. The second pivot section 122is located adjacent to the pressing section 121 and pivotally connectedto the first pivot section 111, such that the handle member 120 isturnable about the second pivot section 122 to move between a closedposition, as shown in FIG. 1, and a pulled-out position, as shown inFIG. 2. The pressing section 121 has a closing edge 121A and apulling-out edge 121B. As shown in FIG. 3, a vertical distance D1between the pulling-out edge 121B and the second pivot section 122 islarger than a vertical distance D2 between the closing edge 121A and thesecond pivot section 122. However, it is not necessary for the verticaldistance D1 to be larger than the vertical distance D2. In otherpossible arrangements, the vertical distance D1 between the pulling-outedge 121B and the second pivot section 122 can be equal to or smallerthan the vertical distance D2 between the closing edge 121A and thesecond pivot section 122.

When the handle member 120 is in the closed position, the closing edge121A is in contact with or located adjacent to the first partitioningwall 210. When the handle member 120 is in the pulled-out position, thepulling-out edge 121B is in contact with or located adjacent to thefirst partitioning wall 210 and the abutting section 112 is movedforward relative to the first partitioning wall 210 by a pullingdistance, which has relation to the vertical distance D1 between thepulling-out edge 121B and the second pivot section 122 and the verticaldistance D2 between the closing edge 121A and the second pivot section122. The pulling distance can be in the range of, for example, 0.5 mm to500 mm.

In the first embodiment, when the handle member 120 is in the closedposition, it is located perpendicular or non-parallel to the firstpartitioning wall 210. On the other hand, when the handle member 120 isin the pulled-out position, it is located in parallel ornon-perpendicular to the first partitioning wall 210.

As can be seen in FIGS. 1 and 2, the abutting section 112 is in the formof an L-shaped arm for abutting against, for example, a rear side of thecorresponding apparatus 300. When the pulling member 110 is movedforward, the abutting section 112 also pushes the correspondingapparatus 300 forward. However, it is understood the abutting section112 is not necessarily limited to the L-shaped arm but can be otherdifferently shaped structures, such as a hook, a latch or a steppedstructure.

In the first embodiment, the first partitioning wall 210 is provided onone side facing the second partitioning wall 220 with a guide rail unit211, to which the pulling member 110 is movably coupled, so that thepulling member 110 can be moved relative to the first partitioning wall210 in a direction away from the circuit board 400 and toward theopening of the object.

When the handle member 120 is operated to turn from the closed positionto the pulled-out position, since the vertical distance D1 between thepulling-out edge 121B of the pressing section 121 and the second pivotsection 122 is larger than the vertical distance D2 between the closingedge 121A of the pressing section 121 and the second pivot section 122,the pulling member 110 is brought by the handle member 120 to moveoutward relative to the first partitioning wall 210. At this point, theabutting section 112 pushes the corresponding apparatus 300 forward tothereby separate the latter from the connection port 410 and bring afront side of the corresponding apparatus 300 to extend beyond the firstand the second partitioning wall 210, 220. Then, the handle member 120can be further outward pulled by a predetermined distance for thecorresponding apparatus 300 to expose more from the opening of theobject and a user can conveniently remove the corresponding apparatus300 from the object with one hand.

Please refer to FIG. 4. The first pivot section 111 and the second pivotsection 122 are pivotally turnably connected to each other via a shaft150. However, it is understood the first and the second pivot section111, 122 can be otherwise connected together via a hinge structure or beengaged with each other via an engaging structure.

The pulling member 110 is provided with a first limiting unit 113. Whenthe handle member 120 is located at the pulled-out position, the firstlimiting unit 113 interferes with a second limiting unit 212 provided onthe first partitioning wall 210 to limit a maximum length by which thepulling member 110 can be pulled out beyond the first partitioning wall210. In the first embodiment, the first limiting unit 113 is anelongated hole, and the second limiting unit 212 is a protruded bodyadapted to be correspondingly received in the above-mentioned elongatedhole. In practical implementation of the present invention, theprotruded body can be a screw, a nut or a rivet locked to the firstpartitioning wall 210. It is understood the first limiting unit 113 andthe second limiting unit 212 are not necessarily limited to theabove-described structure. For example, the first limiting unit 113 canbe otherwise an elongated slot, while the second limiting unit 212 canbe a hooked body adapted to be correspondingly received in the elongatedslot. Alternatively, the second limiting unit 212 can be an elongatedhole or an elongated slot, while the first limiting unit 113 can be aprotruded body or a hook adapted to be correspondingly received in theelongated hole or the elongated slot.

The pull-out aiding device 100 can further include a shock-absorbingmember 140, which is disposed on one side of the handle member 120facing toward the corresponding apparatus 300 to avoid impact of thehandle member 120 on the corresponding apparatus 300. Theshock-absorbing member 140 can be, for example, a piece of foam rubber,sponge or other similar soft material or elastomer.

As can be seen in FIGS. 4 and 5, the pull-out aiding device 100 canfurther include a releasable fastening element 130, which is movablyconnected to the operating section 123 of the handle member 120. Thereleasable fastening element 130 includes a latch 131 for engaging witha latch hole 221 provided on the second partitioning wall 220 to holdthe handle member 120 to the closed position. Also, the releasablefastening element 130 can include a grip portion 132 that is raised froman outer surface of the releasable fastening element 130.

In the illustrated first embodiment, the pulling member 110 or thehandle member 120 can be made of a metal material or a plastic material.

Please refer to FIGS. 6 and 7, in which the first and second limitingunits for a first variation of the pull-out aiding device 100 are shown.According to the first variation, the first limiting unit 113 includestwo flanged bosses 113A, 113B, and the second limiting unit 212 includestwo quick-release guide rails 212A, 212B that are associated with thetwo flanged bosses 113A, 113B in a one-to-one correspondence. As can beseen in FIGS. 6 and 7, the two flanged bosses 113A, 113B are movable inalong the corresponding quick-release guide rails 212A, 212B.

In addition, the releasable fastening element 130 can have more than onelatch 131. In the illustrated first variation of the first embodiment,there are shown two latches 131. Correspondingly, the secondpartitioning wall 220 can be provided with more than one latch hole 221(not shown in FIGS. 6 and 7) for the latches 131 to engage with. Thereleasable fastening element 130 further has two locating stoppers 134,which are adapted to abut against a front edge of the secondpartitioning wall 220, so that the releasable fastening element 130 andthe second partitioning wall 220 are held in place relative to eachother.

Please refer to FIGS. 6, 7 and 8. In the first variation of the firstembodiment, the flanged bosses 113A, 113B respectively have a bodyportion 1131 and a flange portion 1132 formed around a free end of thebody portion 1131. The quick-release guide rails 212A, 212B respectivelyhave a rail portion 2121 and a quick-release hole portion 2122communicable with the rail portion 2121. The body portions 1131 of theflanged bosses 113A, 113B are separately movably received in thecorresponding rail portions 2121. The flange portions 1132 of theflanged bosses 113A, 113B have a diameter larger than a diameter of thebody portions 1131 and a width of the rail portions 2121, so that theflanged bosses 113A, 113B are limited to move only within thecorresponding rail portions 2121. Also, the diameter of the flangeportions 1132 is smaller than a diameter of the quick-release holeportions 2122. When the flanged bosses 113A, 113B are moved in the railportions 2121 to positions corresponding to the quick-release holeportions 2122, the flange portions 1132 can be moved out of thequick-release hole portions 2122, allowing the pull-out aiding device100 to be detached from the first partitioning wall 210.

Further, a distance between the two flanged bosses 113A, 113B is largerthan a distance between the two quick-release hole portions 2122 of thetwo quick-release guide rails 212A, 212B. Therefore, as shown in FIGS. 9and 10, the two flanged bosses 113, 113B would not simultaneouslydisengage from the two quick-release guide rails 212A, 212B. Preferably,on the quick-release guide rail 212B, the quick-release hole portion2122 is arranged at a front end of the rail portion 2121, i.e. a pointon the quick-release guide rail 212B that is closest to the second pivotsection 122; and on the quick-release guide rail 212A, the quick-releasehole portion 2122 is arranged at a point on the rail portion 2121 thatis located behind the front end of the rail portion 2121 by apredetermined distance. Accordingly, when the pulling member 110 ispulled outward relative to the first partitioning wall 210, the flangedboss 113A will reach at the quick-release hole portion 2122 of thequick-release guide rail 212A first, allowing the flange portion 1132 ofthe flanged boss 113A to move out of the quick-release hole portion 2122of the quick-release guide rail 212A. Thereafter, when the pullingmember 110 is further pulled outward for the flanged boss 113B to reachat the quick-release hole portion 2122 of the quick-release guide rail212B, the flange portion 1132 of the flanged boss 113B can be easilydisengaged from the quick-release hole portion 2122 of the quick-releaseguide rail 212B, allowing the pull-out aiding device 100 to be fullydetached from the first partitioning wall 210.

As can be seen in FIG. 11, the pulling member 110 can have a bentsection 115, which is located adjacent to the first pivot section 111and inclined toward the first partitioning wall 210 by 2 to 90 degrees.The bent section 115 is provided with a male foolproof retainer 1151 forensuring correct mounting of the corresponding apparatus 300 in theobject. That is, when the corresponding apparatus 300 is correctlymounted, the abutting section 112 and the foolproof retainer 1151 arepressed against two opposite end surfaces of the corresponding apparatus300. On the other hand, in the case the corresponding apparatus 300 isnot correctly mounted in the object, the foolproof retainer 1151interferes with the corresponding apparatus 300 and the pull-out aidingdevice 100 could not be pushed into the object. And, when the pullingmember 110 has not yet been pulled outward, the bent section 115 ispushed by the first partitioning wall 210 against the correspondingapparatus 300 and is accordingly located in parallel to the firstpartitioning wall 210. On the other hand, when the pulling member 110 isoutward pulled relative to the first partitioning wall 210 and the bentsection 115 is exposed from the object, the bent section 115automatically inclines outward relative to the corresponding apparatus300 and the foolproof retainer 1151 does not hinder the removal of thecorresponding apparatus 300 from the object, allowing the correspondingapparatus 300 to be pulled out smoothly.

According to the present invention, the whole handle member 120 can bemade of a plastic material and can have a window formed thereon. Via thewindow, the corresponding apparatus 300 can be seen from outside of thepull-out aiding device 100.

As shown in FIG. 6, the releasable fastening element 130 can beconfigured to have two latches 131 and two locating stoppers 134. Thelocating stoppers 134 are adapted to abut against a front edge of thesecond partitioning wall 220 and thereby hold the releasable fasteningelement 130 and the second partitioning wall 220 in place relative toeach other. In the illustrated first variation of the first embodiment,the releasable fastening element 130 is connected to the operatingsection 123 via a plurality of compression springs.

Please refer back to FIG. 4. The shaft 150 mounted between the firstpivot section 111 of the pulling member 110 and the second pivot section122 of the handle member 120 has an elastic element fitted thereon. Theelastic element elastically presses against the pulling member 110 andthe handle member 120, such that the handle member 120, once beingopened, can be automatically turned by the elastic element to restore toits original position. The elastic element can be a helical spring, atorsion spring, an elastic cylinder or a sheet spring.

As can be seen in FIG. 11, the handle member 120 can further include areturn hook 129, which can be arranged at an end of the handle member120 having the second pivot section 122 formed thereat. Meanwhile, thefirst partitioning wall 210 is correspondingly provided with a returnhook hole (not shown), to which the return hook 129 is hooked when thehandle member 120 is closed.

Please refer to FIGS. 12 and 13, in which a pull-out aiding device 100according to a second embodiment of the present invention is shown.Unlike the pull-out aiding device 100 of the first embodiment, of whichthe handle member 120 is located corresponding to the opening of theobject, the pull-out aiding device 100 of the second embodiment ismovably mounted to an outer surface of the first partitioning wall 210.In this case, the first partitioning wall 210 is formed with a receivingrecess 213, in which a window is provided. The pulling member 110 isextended through the window with the abutting section 112 of the pullingmember 110 being pressed against the rear side of the correspondingapparatus 300.

The handle member 120 is pivotally turnable about the second pivotsection 122 to move between a closed position, as shown in FIG. 12, anda pulled-out position, as shown in FIG. 13. When the handle member 120is in the closed position, the closing edge 121A is in contact with orlocated adjacent to the first partitioning wall 210; and when the handlemember 120 is in the pulled-out position, the pulling-out edge 121B isin contact with or located adjacent to the first partitioning wall 210and the abutting section 112 is pulled to move forward by a distancerelative to the first partitioning wall 210.

According to the second embodiment, when the handle member 120 is in theclosed position, it is located in parallel or non-perpendicular to thefirst partitioning wall 210; and when the handle member 120 is in thepulled-out position, it is located perpendicular or non-parallel to thefirst partitioning wall 210.

Similar to the first embodiment, when the handle member 120 of thepull-out aiding device 100 according to the second embodiment isoperated to turn from the closed position to the pulled-out position,since the vertical distance between the pulling-out edge 121B of thepressing section 121 and the second pivot section 122 is larger than thevertical distance between the closing edge 121A of the pressing section121 and the second pivot section 122, the pulling member 110 is broughtby the handle member 120 to move forward toward the opening of theobject. At this point, the abutting section 112 pushes the correspondingapparatus 300 forward to thereby separate the latter from the connectionport 410 and bring a front side of the corresponding apparatus 300 toextend beyond the first and the second partitioning wall 210, 220. Then,the handle member 120 can be further forward pulled by a predetermineddistance for the corresponding apparatus 300 to expose more from theopening of the object and a user can conveniently remove thecorresponding apparatus 300 from the object with one hand.

In the second embodiment, the abutting section 112 is in the form of anL-shaped arm for abutting against the rear side of the correspondingapparatus 300. When the pulling member 110 is moved forward, theabutting section 112 also pushes the corresponding apparatus 300forward. However, it is understood the abutting section 112 is notnecessarily limited to the L-shaped arm but can be other differentlyshaped structures, such as a hook, a latch or a stepped structure.

Referring to FIGS. 14, 15 and 16, in which a first variation of thesecond embodiment is shown.
